Abstract: The method comprising at least one Access Point (AP) with a single half duplex radio transceiver allowing the transmission from said AP to a plurality of associated stations connected to any of said two wireless networks, said two wireless networks operating at different frequency channels. Embodiments of the method in order to create said two wireless networks comprises said at least one AP updating a plurality of beacon parameters from a beacon frame at each change of channel frequency of said half duplex radio transceiver. The system of the invention is adapted to implement the method of the invention.

Abstract: It comprises switching on or switching off at least part of said radio access node, such as a femtonode functionality radio section and/or other radio sections, as a function of, respectively, the reception by said radio access node, of a radio signal transmitted by a wireless portable processing device, or the absence of such a reception, where said radio signal is a low-power radio signal transmitted by a low-power radio interface of said wireless portable processing device.
